[Guide][How-To]Fix (Eaccess) Permission Denied error when writing data on sd card

Hi, after updating to android 4.2.2, I encountered the Eaccess Permission Denied error when an app tried to write into the sd card, making the card read-only. So this is a guide to fix that problem.

Use this fix at your own risk

Requirements:
Device must be rooted
Root Explorer installed

Fixing the problem:
Using root explorer navigate to System/etc/permissions
Open platform.xml using root explorer's Text Editor
Find the permission "Write_External_Storage" and there will be the permission group: "sdcard_rw"
Add another group directly under that one: <group gid="media_rw" />
Save changes made in the file and exit
Reboot your device
Done! Now apps have the permission to write data on the external sd card.
Edit: Note that I didn't come up with this solution myself, I found it on a forum (can't remember which one), so thanks to the user who found the solution to this problem.

I'm with you southsamurai - I'm not a complete noob but this one has me stumped, my guess is our situation has nothing to do with the contents of platform.xml because even with root access I can't save changes to it...

But I may be wrong... Did you fix your issue somehow?

Hi guys

I just have my second 802w, this one is coming from UK , it is Kitkat 4.4 + sense 6.
I rooted it and recovery is twrp 2.7
The bootloader says "tampered" + "unlocked"

No way to change Platform.xml even by flashing through recovery usig a zip. It says succeed but same old file after reboot.
If I use the nexapp sdfix, it crashes after "continue" and reboot.
Same if I use a es explorer or total commander, when I push save, black screen + reboot.

It seems there is an additionnal protection on those last updated uk 802w

Anybody has a clue?

I tried this on my nexus 5 and still get the error...

To anyone not getting the change to stick, make sure in ES file explorer you turn root explorer on in the menu on the left hand side. You then need to tap root explorer in order to switch the file path /system to rw before making your changes in the text editor.

If you manage to get further than I did, please write back with any tips!

I used Total Commander instead of Root Explorer and I was able to save the file after I made the changes...and it worked fine

I would like to thank also Stuart D
"Use Total Commander (with 'root' enabled in options).
Edit the file using the built-in editor "Totalcmd-Editor"
When you save, it will ask to remount drive; press OK.
Remember to reboot afterwards."

Thank you very much! It worked on my Note 3 Dual Sim N9002 with Android 5.0.
